SPECIFICATION forming part of Letters Patent No. 287,201, dated October 23, 1883. Application filed July 24, 1882. (No modell) To all whom it may concern.-

' Be itknown that I, WILLIAM STUART WAL- COTT, of New York Mills, county of Oneida,

.State of New York,,have invented an Improvement in WVarping-Machines, of which the fol lowing description, in connection with the accompanying drawings, is a specification.

This invention relates to that class of warping-machines known as the. chain-warper, in which the warps are taken from spools and made into a chain, to be dyed or bleached.

My invention consists in improvements in the reed for separating the threads while the lease is being taken, the said reed being composed of dents and thread-rests, the top or cap of the reed, with its attached rests, being made removable for the introduction of the proper number of threads into thespacesbetween the dents of the reed, thus avoiding drawing the ends through the said spaces by hooks, which, as now practiced, is a very tedious and slow operation.

My invention also consists in means, as will be hereinafter described, whereby the movement of the mass of yarn is started and stopped gradually, thus avoiding sudden jerks or strains, which, if suffered to break a thread, cause very great trouble; and by these devices I avoid slack in the yarn and dispense with the usual take-up or drop rolls. The chain of warp will have two kinds of leases taken in itviz., the weavers lease, when every alternate thread is to be lifted and separated from the thread next to it, and the beamcr s lease, wherein a greater number of threads are introduced into each reed-space, one half of which are to be separated from the other The reed for the beamcrs lease is much coarser than the weaverslease reed.

Figurelrepresentsin topviewasufficientportion of a chain-warping machine to illustrate my invention, the warp being shown in dotted lines. Fig. 2 is a side elevation thereof, a part of the framework, the belt for driving the delivery-rolls, and the can at the sideof it being broken out to show the parts beyond them, the said figure showing the warp in dotted lines; Fig. 3, a left-hand end view of Fig. 2; Figs. 4, 5, and 6, enlarged details of the de vices for automatically stopping the machine when the leases are to be taken; Fig. 7, a detail of part of the reed for taking the weavers lease; Fig. 8, a detail ofpart of the reed for taking the beamers lease, with the cap removed for the introduction of the warp threads, and Figs. 9 and 10, sections of the reeds, showing warp-threads therein as being pressed against the thread-rests to form a lease.

The warp-threads, (shown in dotted lines, Fig. 2, at a,) held on suitable spools, (not shown,) will be extended through holes in the usual hole board or plate, A, a-thread in each hole, and

thence over the measuring-roller B, under roller 0, which depresses the warp on roller B, and through between the dents of theweavers reed E and the beamers reed D, over roller F, down under and up about the warp-feeding or friction drum G, under the roller H, up over the carrier-roll J, between the warp-chain condensing or drawing rollers K L, which draw the warp-threads closely against the drum G, so that the friction of the latter on the warp is sufficient to feed the warp forward, andthence about the roller-guide M, the warp passing from said rollers K L and guides being contracted or condensed into a chain, as at b, and passing thence through delivery-rolls N N into the usual can, P; or it may be a bag lo-' cated at the side of the frame of the machine, from which can it is taken to be dyed.

In Fig. 1 the dotted lines a show the warp as leaving the roller J, and as being contracted between pins 30, (see Figs. 1 and 3,) located near the rollers K L. Power to drive the machine will be applied by a suitable belt (not shown) on the fast pulley c, secured to the short shaft 0 having fast upon it a pinion, c, and loose upon it a belt-pulley, c. The pinion c engages a toothed wheel, c on the shaft 0. of

the drum G, against a greater portion of the surface of which the warp threads are wrapped by the rollers F H. r

The fork o of the belt-shipper, which con- V trols the driving-belt, is secured to the slidebar 0 of the belt-shipper, the said bar having 1 connected with it an upright arm, 0 pivoted at 2 upon a bracket, 3, secured to the floor,

' and joined at its upper end (see Figs. 1 and 3) with connection 0", which may be an endless chain, belt, or cord. The connection 0, extended over and supported by suitable sheaves, may be seized by hand from any side of the machine at any time to move the arm 0 and stop IOO the drum G. This connection a? has attached to it a short chain, c, or it might be a cord, which is also attached to a lever, projecting from a rockshaft, 0, having a weighted arm, -c to turn the said rock-shaft, and pull on the chains 0 and c", and move the belt-shipper to place the driving-belt of the machine on the loose pulley 0 whenever a latch, 6', shall have been automatically released from engagement with a pin, 6 fixed to the frame of the machine, (see Figs. 4 and 5,) the said latch being kept pressed toward the said pin by a spring, 9, and being thrown off the said pin 6 by a pin, 10, on a disk or pin-wheel, 6 fast on a shaft, 6, in a tubular bearing, 12, (see Fig. 6,) the said shaft having at its upper end a bevel gear, e engaged by abevelgear, 6", 011 a short horizontal shaft, 0 having at its opposite end a worm-gear, a engaged by a worm, e", on a second horizontal shaft, 6 at right angles to it, the latter shaft having at its other end a worm-gear, e, engaged by a worm, a, fast on the shaft of the measuring-roller B, before described, which is rotated by the pressure of the warp-threads in con= tact with its periphery.

A certain number of revolutions of the measuringroller B indicates that a certain number of yards of warp have passed over the said roller, and consequently, by gearing of suitable size, the latch e may be automatically released after the passage of any number of yards of warp thread to thus stop the machine at any stated intervals.

The shaft of drum G, opposite the toothed wheel 0, but outside the frame-work A, has a be1t-pu11ey,f, (see Figs. 1 and 3,) which receives a belt, f, extended upward over a smaller pulley, j, on the shaft of roller J, the

said shaft, at the side of pulley f having a.

larger pulley, j, which drives a belt, f tended over a pulley, f on the shaft f, on which is secured the roller L of the chaindrawing rollers K L. The lower roller, L,

acts to draw the chain of warp only when roller K rests with its weight upon the mass of warp on the roll L, and consequently the pressure of more or less of the weight of roll K on the chain of warp will make the said rolls draw the warp more or less closely against and about the drum G.

"Whenever the belt-shipper is shifted to stop the rotation of the drum G, the roller .K is automatically lifted to decrease its pressure upon the warp under it. 7 To do this I have connected the bearings for the shaft of roller K with parts of a connection, 9, extended over sheaves 14 15 16 17 18, and joined the lower end of the said connection with an ear,

of the shipper-bar a, as in Fig. 3, so that as the said shipper-bar is moved to ship the belt from the fast to the loose pulley the roller K is lifted, and when shipped to the fast pulley the roller K is lowered. The motion of the shipper-bar being gradual, the descent of the roller K is gradual, and consequently by shifting the said belt slowly, as may be done by the operator through the connection 0", the chain of warp may have its movement arrested very slowly and started very slowly, thus avoiding all injurious kinking or slack, or such strains in starting which might cause the threads to break, which in this class of machine, wherein a warp stop-motion is not used, and where the warps are for most of their length in a chain, is a very serious difficulty, taking much time to correct.

The latch e is pivoted at 20 upon a slide or latch-carrier, 21, held in guides 22, and provided at its rear end with achain, 23, extended over a sheave, 25, and having attached to it a weight, 24., so that as the latch e is released the weight 24 also acts to draw the latchcarrier backward in the direction of the arrow 27, Fig. 5, and cause the pin 26, connected with the carrier and with the lever 0 to draw or turn the latter at the same time that the weight 0 acts in the same direction, thus causing the lever 0 by its pull on the short chain c, to move the connection 0' and stop the machine, as described.

Thedelivery-rollers N N have their journals held in a yoke or bearingframe, 28, supported at the end of an arm, A, of the framework, and also by a rod, 29, the upper end of which, provided with a suitable head, will be screwed to the ceiling. The shaft of the roller N has a flanged belt-pulley, 30, which receives a belt, 31, passed abouta flanged pulley, 33, on the end of roller J, the said belt, to reach the pulley 30, being bent about the guide-roller 32. Rollers L and N are driven from the roller J, and as the motion of the latter roller is increased or diminished the rotation of the former rollers is correspondingly affected.

The reeds are composed of bottom bars, h, removable top bars or caps, h, thread-rests If, secured to the top and bottom bars, dents h, and side pieces, 7L2. In the reed E, for taking the weavers lease, the thread-rests connected with the bottom bar, h, cover the spaces between every first and second and third and fourth dent, (see Fig. 7,) while the threadrests attached to the top bar cover the spaces between the second and third and the fourth and fifth dents. The dents and spaces between them in the reed for the weavers lease are much more numerous and finer than in the beamer? s reed D. (Shown in Fig. 8.) The caps h of both reeds are made removable, as, shown in Fig. 8, by simply removing the nuts m, and the caps being removed the proper number of warp-threads to be placed into any one reedspace may be quickly and easily counted 011 and dropped into the reed-spaces, and the cap be then again applied, thus avoiding the tedious and s1 ow process of drawing the threads through by means of a hook. The spaces between the from side to side of the machine, as in Figs. 9

and 10, will cause the single threads in the spaces between the dents of the reeds to occupy two different planes just at the rear of the dents of the reed, forming spaces m into which may be extended a thread to keep the lease separated, the rods m during such operation,.being heldby the hooks m.

I do not broadly claim a roller which is lifted from threads to stop their feeding movement when the thread breaks.

I have shown two sets of hooks. m, for each reed, either of which may be used, according to whether the lease is formed by pressing the warp upward or downward.

I claim- 1. Thewarp-feeding drum G, means to move it, the carrier-roller J and roller L, and suitable means to move them, and the pressingroller K, combined with belt-shipping mechanism, and connection 9, between the said pressing-roller and belt-shipping mechanism,

.to operate substantially as and for the puro poses described.

2. The belt-shipper bar, fast and loose pulleys, shaft 0 the drum G, and means to drive the said drum from the said shaft, combined with endless connecting device 0, and means to sup- 3 5 port it and to connect it with and to move the said shipper-bar, substantially as described.

3. The belt-shipper bar, the endless connection 0 and means to support it, combined with V the measuring-roller, worm e worm-gear e 40 'shaft 6 worm 6, gear e, shaft 6 gears e e,

shaft 6*, pin-wheel, latch e, operated by it, and connecting device 6, as and for the purposes set forth.
